The Diphenylamine-4-Sulfonic Acid Barium Salt Analytical Grade ACS by Dinâmica, available at LojaLab, is the barium salt of diphenylamine-4-sulfonic acid used as a redox indicator in volumetric titrations. When the solution potential passes through the system transition range, a violet to red-violet color appears and supports endpoint detection. The reagent is traditionally associated with determinations of iron(II) using dichromate in acidic medium and with other redox methods that explicitly specify it.
Characteristics
- Redox indicator based on the barium salt of diphenylamine-4-sulfonic acid
